Change it in your template.

Find your theme’s logged-in.php file. Look for bb_profile_link() and change it to

bb_profile_link( "Use my text instead" );

(If you’re using the default theme, first copy the bb-templates/kakumei/ directory to a new directory called my-templates/my-theme/, activate that new theme from the Presentation admin panel and edit those files instead).
